Supersymmetric intersecting D6-branes and chiral models on the T^6/(Z_4 x Z_2) orbifold

Abstract

Intersecting D-brane worlds provide phenomenologically appealing constructions of four dimensional low energy string vacua. In this talk, a Z_4 x Z_2 orbifold background is taken into account. It is possible to obtain supersymmetric and stable chiral models. In particular, a three generation model with Pati-Salam gauge group and no exotic chiral matter is presented.
